The cropping options are only available for pictures, screenshots, and characters.

(Another way to crop an object is to go to the Format tab on the ribbon, click Crop, then drag the black cropping handles that appear on the edges of the object.)

Reset

Click this button to reset the object to its original size.

This option is only available for pictures, screenshots, characters, videos, and Flash files.

Positioning Objects

Although it's easy to move an object on your slide just by dragging it, sometimes you need more control over its exact position.

Select the Position tab on the left edge of the window, then enter pixel values in the Horizontal and Vertical location fields. Use the From selectors to choose a relative location.

Adding Alternate Text to Objects

Use the Accessibility tab on the left edge of the window to set accessibility options for screen readers and keyboard navigation.

By default, screen readers announce each object on the slide according to its name in the timeline panel. Here are two ways to modify this behavior:

Object is visible to accessibility tools: This box is marked for all objects by default. Uncheck it if you don’t want the selected object to be detected by screen readers or part of the keyboard navigation. For example, if you have objects on the slide that don't contribute to the meaning of the content, such as aesthetic elements (rectangles, lines, etc.), it's a good idea to uncheck this box for those objects.

Alternate text: If you'd like screen readers to use a description that's different from what appears in the timeline panel, enter that alternate text here.

Another way to add or edit alternate text is to use the Tab Order window.

Adding Closed Captions to Narration and Videos

Also on the Accessibility tab, you can create, edit, import, delete, and export closed captions for audio tracks and videos. Just click the icons to the right of Captions.
